Abstract:
A system and method for fast roaming in one or more enterprise fabric network. The fast roaming involves correlation operations performed in one or more databases managed by control plane of the fabric network to update routing locator entries associated with L2-VNID and L3-VNID in one or more databases when a client moves from behind a first switch to behind a second switch. In some embodiments, the control plane finds the L3-VNID from the L2-VNID. The L3-VNID is used to search for all IP addresses corresponding to a client-MAC. At least new routing locator value that is used in the routing locator entries is provided to the first switch, the second switch, and border nodes associated with the fabric network.
